- 1are defined to work on specific data types and that not all operators are synthesizable.operators
- 2Verilog Operators• Bitwise Logic Operators
• Reduction Logic Operators
• Boolean Logic Operators
• Relational Operators
• Conditional Operators
• Concatenation Operator
• Replication Operator
• Numerical Operators - 3hese perform logic functions on individual bits. The inputs to the operation are single bits, and the output is a single bit. In the case where the inputs are vectors, each bit in the first vector is operated on by the bit in the same position from the second vector. If the vectors are not the same length, the shorter vector is padded with leading zeros to make both lengths equal.• Bitwise Logic Operators
- 4A reduction logic operator uses each bit of a vector as individual inputs into a logic operation and produces a single bit output. Verilog contains the following reduction logic operators.• Reduction Logic Operators
- 5A Boolean logic operator returns a value of TRUE (1) or FALSE (0) based on a logic operation of the input operations. These operations are used in decision statements.• Boolean Logic Operators -
- 6A relational operator returns a value of TRUE (1) or FALSE (0) based on a comparison of two inputs.• Relational Operators -
- 7Verilog contains a conditional operator that can be used to provide a more intuitive approach to modeling logic statements.• Conditional Operators -
- 8In Verilog, the curly brackets (i.e., {}) are used to concatenate multiple signals. The target of this operation must be the same size as the sum of the sizes of the input arguments.• Concatenation Operator
- 9Verilog provides the ability to concatenate a vector with itself through the replication operator. This operator uses double curly brackets (i.e., {{}}) and an integer indicating the number of replications to be performed. The replication syntax is as follows:• Replication Operator
- 10Verilog also provides a set of numerical operators as follows:• Numerical Operators
- 11Operator Precedence
- 12Each of the logical operators can be used in conjunction with concurrent signal assignments to create individual combinational logic circuitsContinuous Assignment with Logical Operators
- 13allows us to describe a continuous assignment using Boolean conditions that affect the values of the result. In this approach, the conditional operator (?) in conjunction with the continuous assignment keyword assign is usedContinuous Assignment with Conditional Operators
- 14Verilog provides the ability to model gate delays when using a continuous assignment. The # is used to indicate a delayed assignment.• Continuous Assignment with Delay
